Ecosystem
In an ecosystem living things interact with other living and non living things in a shared environment
Population
When members of a species live in a specific area and share the same resources, these individuals form a population
Community
When populations of different species live in the same area form an community
Genus
biological classification ranking between family and species
Symbiosis
Another type of interdependence is called symbiosis (sym meaning together; biosis meaning living) which is an association between members of different species
Commensalism
One of the participating organisms benefits but the other does not. However there’s no harm done to the second organism
Mutualism

Inter species competition
Happens when two or more species need the same resource
Niche

What does an organisms niche include
An organisms niche describes what it eats, and what eats it. It’s habitat, nesting site or range. And the affect on both the populations
Resource partitioning
Dividing up the resource among them what is known as resource partitioning. Doesn’t always involve food.
